206 no doubt.
i fown both of them, both as a pass and as a pilot, 206 its a work horse. True ec is more confortable for the pass, but 206 its so reliable and its so a noble machine and a joy to fly. Its slower though but its a very safe 'the safest single engine aircraft in the world' and it keeps its record for a long time. Maintainance its not hard and well documented, your mechanic can do a lot more to it than on the EC to fix it on the field.
More technology on the EC, quiter for sure, but the penalty for it its power. Although jet rangers are not a loader heli, it can carry more weight and be more forgiving in altitude and hot wx.
Its just my POV.
I flown both of them to see what i would buy, and got a 206. Ohh, operation cost is also lower. (at least in mx)
